Abstract: The TRIZ theory was applied to analyze the causal chain of zirconia ceramic products contaminated by the atmosphere in the furnace,and the key problems were determined,and the optimal innovation scheme was generated under the guidance of TRIZ tools:when the furnace temperature is below 1 155 ℃,an oxygen enrichment pump is used to introduce oxygen-rich air into the furnace chamber;when the furnace temperature is above 1 155 ℃,the oxygen enrichment pump is turned off to reduce the oxygen content in the furnace chamber;a composite material is used to fabricate a sealed sagger,and the zirconia ceramic products are placed into the sagger in order to separate the MoO₃ contaminated atmosphere in the furnace chamber from the zirconia ceramic products.

Key words: TRIZ theory, high-temperature furnace chamber, contamination, zirconia ceramics
